Rhabdometra alpinensis n.sp. is described from white-tailed ptarmigan (Lagopus leucurus altipetens) from Colorado. A key to the known species of Rhabdometra is included. Rhabdometra terricoli Sharma, 1947 is transferred to Anonchotaenia Cohn, 1900. Rhabdometra alpinensis, R. nullicollis, and R. tomica are similar in having the genital pore anterior to the middle of the lateral margin of the proglottid and the testes arranged in one group on each side of the ovary. There are 30–49, 60, and 12–30 testes, respectively. In R. alpinensis, the cirrus pouch is nearly equal in diameter throughout its length, whereas in the other two species, it is narrow distally and broad proximally.

Orthezia cheilanthi, n. sp.—Adult ♀ Length, 3.5 mm. Width, 3-3.5 mm. Length + ovisac, 6-8 mm. Width of Ovisac 3-4 mm. Body above covered with whtie secretion, which forms lateral and sub. dorsal longitudinal keels. A well-defined subdorsal furrow between the keels and the lateral margin formed by 3 or more rows of paltes; these are smaller than the projecting marginal plates, which are flattened; caudal plate and the 3 or 4 plates on each side of it very little longer than the lateral plates. The structure of the secretion is compact; in most of the other species of Orthezia it is fluffy.

Eighteen species of the galatheid genus Galathea Fabricius, 1793 from Chinese waters are reported in the present paper based on material in the collection of the Marine Biological Museum (MBM) in the Institute of Oceanology, Chinese Academy of Sciences, Qingdao (IOCAS), including two new species (G. babai n. sp., G. sinensis n. sp.) and eight species new to Chinese waters (G. anepipoda Baba, 1990, G. consobrina De Man, 1902, G. coralliophilus Baba & Oh, 1990, G. guttata Osawa, 2004, G. inconspicua Henderson, 1885, G. pilosa De Man, 1888, G. ternatensis De Man, 1902, and G. whiteleggii Grant & McCulloch, 1906). Galathea babai n. sp. can be distinguished from all the other congeneric species by the presence of a strong median protogastric spine. Galathea sinensis is distinguished from its nearest congener, G. multilineata, by having more numerous transverse striae on the carapace, the lateral margin of the carapace with only one instead of four spines behind the posterior cervical groove, the P1 fingers distally ending in incurved spines that cross when occluded (instead of being spooned), and a much shorter cheliped (especially the carpus length relative to breadth). To date, 26 species of Galathea Fabricius, 1793 have been recorded from Chinese waters, including the two new species.

Intestinal Trematodes

AbstractSpecimens of the fishes Lethrinus nebulosus Forsskål (Lethrinidae) and Diplodus noct Valenciennes (Sparidae) were caught in the Red Sea off the coast of Sharm El-Sheikh, South Sinai, Egypt. Ten (33%) and 12 (24%) of these fishes, respectively, were found to harbour intestinal trematodes. L. nebulosus was parasitised by Pachycreadium lethrini sp. nov. (Opecoelidae) and D. noct by Pseudometadena aegyptensis sp. nov. (Cryptogonimidae). P. lethrini sp. nov. is unique in having distinctly unequal testes, contiguous gonads arranged obliquely in the right side of hindbody and a small egg size. However, it differs from each of the other three species of the genus in several other features: from P. gastrocotylum (Manter, 1940) Manter, 1954 in having a smaller sucker ratio and vitelline follicles terminating anteriorly at the level of intestinal bifurcation; from P. carnosum (Rudolphi, 1819) Cortini et Ferretti, 1959 in having a smaller body, a smaller sucker ratio, a genital pore situated ventrally to the anterior border of pharynx, a pretesticular ovary and vitelline follicles extending anteriorly to the level of intestinal bifurcation; and from P. lerneri Sogandares-Bernal, 1959 in having a larger body, a smaller sucker ratio and an unlobed ovary. P. angolensis Aleshkina et Gaevskaya, 1985 is considered an invalid species in Pachycreadium. P. aegyptensis sp. nov. is similar to P. celebesensis Yamaguti, 1952, but mainly differs in having a larger pharynx, a much shorter oesophagus, extensive vitelline acini and a shorter seminal vesicle. Pachycreadium Manter, 1954 and Pseudometadena Yamaguti, 1952 are briefly reviewed.

A new riffle beetle, Zunielmis pax gen. et sp. nov., is described from Colombia (Vichada, Puerto Carreño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure of mesosternum, mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed. Drawings and photographs of the adult habitus, distinctive morphological characters, and male and female genitalia are provided.

A New Species

A new species of Benthana Budde-Lund, 1908 is described from southern Brazil. Benthana cairensis sp. nov. is distinguished from the other species in the genus by having 17 aesthetascs on the antennula and the elongated male pleopod 1 exopod with a lobe on the inner lateral margin and up to six setae on the outer lateral margin. The new species most resembles B. olfersii (Brandt, 1833), but may be distinguished by lacking the lobe with six setae on the internal margin of the proximal extremity of the merus of pereiopod 7. Furthermore, we include B. olfersii in the subgenus Benthanoscia based on the examined material as described herein.

New Genus And Species

A new genus and species of fossil soldier beetle Markus karenae gen. et sp. nov. is described and illustrated from Eocene Baltic amber. Its morphological characteristics place it in the taxonomic position of the subfamily Silinae. It is characterized by a particular lateral pronotal shape with two difform processes, pronotum slightly longer than wide, with a blunt and evident angle near the basal angles, anterior and posterior margins flat and with shallow punctation, and lateral margin strongly granulose and in relief. Furthermore, each of its legs has a claw with one acute tooth at the base, except for the posterior legs where the tooth appears to be blunt. The new taxon is morphologically compared with the other fossil representatives of Silinae from Baltic amber, and with extant Palearctic genera.

Stromatoporoids are the principal framebuilding organisms in the patch reef that is part of the reservoir of the Normandville field. The reef is 10 m thick and 1.5 km2in area and demonstrates that stromatoporoids retained their ability to build reefal edifices into Famennian time despite the biotic crisis at the close of Frasnian time. The fauna is dominated by labechiids but includes three non-labechiid species. The most abundant species isStylostroma sinense(Dong) butLabechia palliseriStearn is also common. Both these species are highly variable and are described in terms of multiple phases that occur in a single skeleton. The other species described areClathrostromacf.C. jukkenseYavorsky,Gerronostromasp. (a columnar species), andStromatoporasp. The fauna belongs in Famennian/Strunian assemblage 2 as defined by Stearn et al. (1988).

Informal Approach

(Ed. note:Encouraged by the success of the more informal approach in Christy's presentation, we tried an even more extreme experiment in this session, I-D. In essence, Kraft held the floor continuously all morning, and for the hour and a half afternoon session, serving as a combined Summary-Introductory speaker and a marathon-moderator of a running discussion on the line spectrum of cepheids. There was almost continuous interruption of his presentation; and most points raised from the floor were followed through in detail, no matter how digressive to the main presentation. This approach turned out to be much too extreme. It is wearing on the speaker, and the other members of the symposium feel more like an audience and less like participants in a dissective discussion. Because Kraft presented a compendious collection of empirical information, and, based on it, an exceedingly novel series of suggestions on the cepheid problem, these defects were probably aggravated by the first and alleviated by the second. I am much indebted to Kraft for working with me on a preliminary editing, to try to delete the side-excursions and to retain coherence about the main points. As usual, however, all responsibility for defects in final editing is wholly my own.)

The Continuum

Pecker:The topic to be considered today is the continuous spectrum of certain stars, whose variability we attribute to a pulsation of some part of their structure. Obviously, this continuous spectrum provides a test of the pulsation theory to the extent that the continuum is completely and accurately observed and that we can analyse it to infer the structure of the star producing it. The continuum is one of the two possible spectral observations; the other is the line spectrum. It is obvious that from studies of the continuum alone, we obtain no direct information on the velocity fields in the star. We obtain information only on the thermodynamic structure of the photospheric layers of these stars–the photospheric layers being defined as those from which the observed continuum directly arises. So the problems arising in a study of the continuum are of two general kinds: completeness of observation, and adequacy of diagnostic interpretation. I will make a few comments on these, then turn the meeting over to Oke and Whitney.
